AMERICAN COLEOPTERA. * ou 



punctulate, the alternate series, 1-3-5-7, with coarser punches distantly placed 

 Bo-ay beneath less shining, sparsely punctate and pubescent. Prosternal process 

 scarcely prolonged between the coxae. Length .12 inch ; 3 millim. 



This species closely resembles Lecontei It has a smaller thorax, the 

 elytra more deeply striate, the striae more closely punctured, the inter- 

 vals more convex but less punctulate. In Lecontei the clypeus ts en- 

 tirely membranous, in the present species prolonged and corneous, in that 

 species the presternum is distinctly prolonged between the coxae, here 

 scarcely so. As my type of Lecontei. is a % and the present a 9 , it is 

 hardly safe to insist on the clypeal character as a specific one. 



One specimen ? , collected by Dr. W. G. Diet, at Hazleton, Pennsyl- 

 vania. 



DIETTA Sharp. 



At the time of the publication of my Synopsis of the Silphidae I 

 called attention to certain apparent anomalies in the structure of the 

 insect, especially in the structure of the tarsi, which were said to be 

 4-5-5-iointed. Through the kindness of Dr. Sharp I have examined 

 his unique, and found that the specimen was really a monstrosity, there 

 being four joints on one anterior tarsus and five on the other. The 

 genus must, as I suspected, be placed in the series with five joints on all 

 the feet, and is really, as I stated, intermediate between Hydnobxm and 



Anoqrfus. 



STMHYGRAPHIS Lee. 



On the request of Dr. LeConte I have prepared a figure of this very 



peculiar genus of Staphylinidae, allied to Geodromicus of the Homahm. 



It is remarkable in the spinous hairs projecting laterally from the post- 

 ocular re-ion of the head. All the tibiae exhibit curious structure, as 

 shown in°the plate, which characters are, possibly, sexual. Two speci- 

 mens only are known, both of which agree in the details given. 

 It occurs in California.

HISTER Linn. 

 H (PheliBter) gentlll- n. sp.-Oval, convex, black, shining Head and 

 thori sparsely and finely punctulate. Thorax with an entire, well^mpressed 

 «nwXal stria Elytra more sparsely and finely punctured than the thorax, 

 urf^e wh^ rentire'dorsal and a suturol stria, all sharply impressed, the inner 

 dorsTlald sutural joining by an arc ; external snbhumeral entire, internal absent. 

 Epipleur^ unistrilte. Propygidiun. and pygidium sparsely and hnely m.nc- 

 Tured. Presternum convex, the striae distinct, diverging and ascendmg n front. 

 Marginal stria of mesosternum entire. Body beneath sparsely punctulate. Ante- 

 rior tibiae very finely serrulate, Length .10 inch; 2.5 imllim. 



It is not without some little doubt that I refer this species to PheUster.
